For the MTA100 IDC connectors, you could reuse by cutting and soldering the wire, but I would not recommend removing and re-inserting the wire (even on a fresh connector, inserting without the proper tool can easily lead to poor connections -- much more if you reuse a connector that already has it's blades deformed).

+1 on crimper (next driver order from Pololu, throw one in, perhaps?) -- if you don't have one, soldering is better (although a PITA).

I did find out that my cartridge isn't blown as I was grabbing the cartridge with a clothespin after testing it and it just started smoking, so I know it works. 

The thermistor is also intermittently dropping so that needs to be re-done. 

I made a nice little y-connector using the JSTs so that I can connect both fans to the OEM fan connection.  Those connections seem to be stable.  This allows me to switch back to the stock hot-end and use only the one fan on the stepper.

Sorry for hijacking, but it is safe to remove and re-do the connectors from stock to new.  You just have to make sure the connections are solidly crimped and that requires a little bit of time.

What I was wondering is, if I could chop off the connectors from my old hotend and connect them to the E3D?
